Information about 404 blockchain

404

Year 404 (CDIV) was a leap year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Honorius and Aristaenetus (or, less frequently, year 1157 Ab urbe condita). The denomination 404 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Block chain (database)

A block chain is a distributed data store that maintains a continuously growing list of data records that are hardened against tampering and revision, even by operators of the data store’s nodes. The most widely known application of a block chain is the public ledger of transactions for cryptocurrencies, such as bitcoin. This record is enforced cryptographically and hosted on machines running the software.
The technology forms the basis of all cryptocurrencies.
